Bill,

Looks like you've nailed the cooling system design to get near perfect temps on climbout.

Can you tell us about your air intake openings - round/square? Dimensions? Use a smooth plenum behind the intake openings back to the radiator(s) or not? Remind us of your radiator dimensions (thick, wide, high) and brand? Size and design of the big cowl flap?

NOW you come up with this! I already did it the hard way. Pressure recovery was good, and the biggest improvement came from opening up the cowl flap. I made a new one that is about twice the size of the original. Now I can climb out at 25 inches MAP with OAT over 100F, and the oil stays under 200, and the coolant stays about 205. Does that sound reasonable for temps?
